Tungaloy TNGG160408L-P GH110 Turning Insert
PVD Coated GH110 Grade | Precision -P Chipbreaker | 0.8mm Left-Hand Radius
What is the most reliable PVD coated insert for high-wear steel finishing?
The Tungaloy TNGG160408L-P GH110 is a premium left-hand PVD coated carbide insert engineered for high-precision finishing in ISO P (Steel) and ISO K (Cast Iron). Featuring the advanced GH110 grade, this tool offers exceptional flank wear resistance and edge toughness, ensuring dimensional stability across long production cycles. The 0.8mm corner radius (08) provides a robust cutting edge capable of higher feed rates while maintaining superior surface integrity. 100% Made in Japan, it is the industrial benchmark for CNC operators who require repeatable precision in demanding steel turning applications.
GH110 High-Wear PVD
A specialized PVD coating with extreme hardness. It protects the sharp cutting edge against abrasive wear, making it ideal for high-carbon steels and cast iron.
-P Finishing Geometry
The -P chipbreaker is optimized for light depths of cut. It facilitates excellent chip flow, preventing surface marring and keeping the workpiece clear of stringy chips.
0.8mm Robust Radius
Balanced for finishing, the 0.8mm radius offers increased edge strength compared to finer radii, allowing for stable machining even in slightly unstable setups.

Recommended Parameters for GH110
-
Cutting Speed (Vc): 80 - 180 m/min (Balanced Performance)
-
Feed Rate (f): 0.10 - 0.25 mm/rev (Standard Finishing)
-
Depth of Cut (ap): 0.2 - 1.2 mm
*B2B Pro-Tip: The 0.8mm radius is ideal for the final finishing pass in batches where dimensional tolerance is more critical than ultra-high gloss.*
4. Primary Applications
- Precision finish turning of carbon and alloy steels.
- Continuous finishing of cast iron (ISO K) parts.
- Final pass machining for large batches of automotive pins and shafts.
- Excellent for boring bars where chip control is restricted.
5. Tool Compatibility
Standard TN** 1604 interface. Pairs specifically with WTJNL or MTJNL Left-hand external holders. Also optimized for S-WTJNL internal boring bars.

8. FAQ - Precision Tooling Support
Q: When should I choose GH110 over a cermet insert?
A: Use GH110 (PVD Carbide) for finishing where the material is abrasive or if the setup has slight vibration. It is tougher and more resistant to edge chipping than cermet.
Q: Can this insert be used in a standard Right-hand holder?
A: No, this is a Left-hand (L) insert. It must be used with a Left-hand tool holder (WTJNL) for correct chipbreaker performance and edge orientation.
Tech Tip: Surface Excellence with PVD Carbide
Maintain a stable feed rate and ensure proper coolant flow to maximize the life of the **GH110** coating. For the highest surface gloss, keep the cutting speed near the upper limit. **Tungaloy Japan** - Leading the way in precision finishing technology.
